Core Application Scenarios of Two-Plate Clamping Injection Molding Machines

Date:2026-02-03     Click:27

Classified by part size, mold type, and production needs, its applicable scenarios cover everything from micro-precision parts to ultra-large plastic parts, making it the most versatile injection molding machine type. Specific core application scenarios are as follows:

1. Molding of Medium to Large Plastic Parts (Core Main Scenarios)
Suitable for medium to large plastic parts weighing over 500g, such as appliance housings (refrigerator, washing machine panels), automotive interior and exterior trim (bumpers, door panels, dashboards), industrial parts (pallets, turnover boxes), and large daily necessities (trash cans, storage boxes).

Reasons for suitability: The mold opening stroke can reach over 1000mm (up to 3000mm for ultra-large machines), providing a large mold space suitable for large molds; the clamping force is uniform, preventing deformation of large mold plates due to uneven stress, ensuring the dimensional accuracy of the plastic parts; and the mold opening/closing speed is adapted to the motion requirements of large molds.

2. Mass Production of Conventional Plastic Parts with Multi-Cavity Molds (Mainstream Mass Production Scenarios)
Adapted for the mass production of micro/small conventional plastic parts with multi-cavity molds, such as food packaging (cup lids, lunch boxes), small electronic components (charger housings, connectors), and daily necessities (buttons, pen barrels). It is also the preferred model for the mass production of small and medium-sized parts such as eyeglass cases and plastic accessories.

Reasons for Adaptation: No intermediate platen; the mold is directly installed between the moving and fixed platens, making mold installation and debugging simpler. Mold changeover efficiency is 20%~30% higher than three-platen molds. Fast mold clamping response, combined with a high-speed injection system, can compress the molding cycle, adapting to the high-speed mass production needs of multi-cavity molds, resulting in higher uptime.

3. Dedicated Adaptation for Hot Runner Molds (Precision Mass Production Scenarios)
Currently, hot runner molds in the industry are used with two-platen mold clamping machines, suitable for precision plastic parts (such as optical lenses, precision electronic components) and high-requirement mass production plastic parts (such as cosmetic packaging, medical accessories).

Reasons for compatibility: The intermediate plate of the three-plate mill is specifically designed for removing runner material from cold runner molds, while hot runner molds do not have cold runners and do not require an intermediate plate; the two-plate mill has a high mold fit, ensuring accurate gate positioning in hot runner molds, reducing overflow and material shortages, and improving the yield of precision plastic parts.

4. Special Molds / Plastic Part Molding (Specialized Adaptation Scenarios)

Stacked Molds: The uniform clamping force of the two-plate mill can adapt to the multi-cavity stress requirements of stacked molds, achieving "double the output from one mold," and the mold space can meet the installation requirements of stacked molds;

In-mold Insert / Labeling Molds: The large mold opening stroke allows for automated operations such as inserting and labeling by robots within the mold, with no intermediate plate obstructing the process, providing more space for automated operations;

Thick-walled Plastic Parts: Stable clamping force maintains mold fit during the holding pressure stage, effectively reducing defects such as shrinkage marks and bubbles in thick-walled plastic parts.
